(Cl. 292-330) My invention relates to looks. lock half 1 projects laterally as at 8, abutting It is the object of my invention to provide a against the shoulder 9 beneath the flange 10 of lock that is so designed that when once applied the inwardly projecting portion 11, forming the to a structure to be locked, such as an electric bottom of the half 2 of the rock.

The lower portion of the look, who uses a small wire inserted along side 0 the leg of the hasp. It also permits the use of two locking pawls by using the free ends of the springs. With the spring I have there is a double action because when you pull down or push down on the spring on one side, it naturally tightens the tension on the other side. The seat which is on one side of the lock prevents anyone tampering with that side from that particular point as the obstruction on the loop fits into the seat in such a manner that the person tampering would have to go around two different corners to get into the lock, which is impossible. This is the reason for the seat or socket 15 in the casing and the obstruction or shoulders 1'7 on the hasp 18.

I desire to comprehend within my invention such modifications as may be clearly embraced within the claim and scope of my invention.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. In combination, a permanently assembled lock casing, locking means thereon adapted to receive and retain a hasp in said casing, a sleeve on the casing forming a socket, and a lock hasp adapted to be inserted in said casing to be locked therein, and shoulder means on said hasp to fit in the socket to prevent the removal of the hasp completely from the lock and its locking means even though the lock hasp is broken, said socket having a cone-shaped bottom to aid in positioning the hasp.

2. In combination, a permanently assembled lock casing, a sleeve on the casing forming a socket, locking means thereon adapted to receive and retain a hasp in said casing, a lock hasp adapted to be inserted in said casing to be locked therein, means to lock the hasp in the casing, and shoulder means on said hasp to fit in the socket to prevent the removal of the hasp completely from the lock and its locking means even though the lock hasp is broken, said means being located on one leg of the hasp only.

3. In combination in a lock, of interlocking lock casing halves, means to retain said halves in interlocking engagement, a locking means mounted on said half retaining means and an insertable lock hasp adapted to be inserted in said locking means, and retained in position by said locking means, said hasp comprising a U- shaped body having locking faces on its legs, and a shoulder on one of said legs, and means on said lock casing for receiving and engaging said shoulder.

4. In combination in a lock, or" interlocking lock casing halves, means to retain said halves in interlocking engagement, a locking means mounted on said half retaining means and an insertable lock hasp adapted to be inserted in said locking means, and retaining in position by said locking means, said hasp comprising a U-shaped body having locking faces on its legs, and a shoulder on one of said legs, and an outwardly projecting sleeve forming a socket on said lock casing for receiving and engaging said shoulder, said socket having a cone-shaped bottom to guide the leg.

5. In combination in a lock, a pair of interlocking lock halves, means to retain said halves together to form a chamber, a lock means comprising a spring member wound on said retaining means having depending oppositely disposed ends adjacent annular passageways through said lock halves, a U-shaped hasp having its legs projecting into said passageways and having notches on said legs for engaging said locking means, and a shoulder on one of said legs engaging a receptacle in said lock casing halves whereby that leg of the hasp cannot be withdrawn.

6. In combination in a look, a casing having spaced annular passageways therethrough, one of said passageways having an outwardly projecting sleeve forming a large socket having a cone-shaped bottom around the passageway, lock means in said casing extending into said annular passageways and a U-shaped hasp having a shoulder thereon, the legs of which extend into said annular passageways and notches which engage with said locking means While the legs are in such passageways.

7. In combination in a look, a casing having spaced annular passageways therethrough, one of said passageways having an outwardly projecting sleeve forming a large socket having a coneshaped bottom around the passageway, lock means in said casing extending into said annular passageways and a U-shaped hasp having a shoulder thereon, the legs of which extend into said annular passageways and notches which engage with said locking means while the legs are in such passageways, said hasp being of frangible material.

8. In a look, a two-part interlocking casing having hasp-receiving passageways formed therein, one of which is enlarged by extending the casing outwardly to form a socket, a hasp insertible in said passageways having a shoulder projecting into said socket and fitting therein, and a common yielding locking means mounted between said halves of the casing within the casing engaging notches in said hasp where the arms thereof project into said passageways.

9. In a look, a two-part interlocking casing having hasp-receiving passageways formed therein, one of which is enlarged to form a socket, a hasp insertible in said passageways having a shoulder projecting into said socket and fitting therein, and a common yielding locking means mounted between said halves of the casing within the casing engaging notches in said hasp where the arms thereof project into said passageways, said hasp being made of frangible material and having at spaced points portions thereof cutaway to facilitate the breaking of the hasp when subjected to undue strain.

10. In a look, a two-part interlocked casing riveted together, a rivet therefor, means freely mounted thereon comprising a coil spring having laterally extending depending ends extending into hasp-receiving passageways in said casing, a hasp having legs with notches extending into said passageways, the notches having downwardly inclined shoulders engaged by the ends of said spring.
